According to Science Daily, researchers at the Solar Observatory in Big Bear, CA have been taking some pretty detailed photos of the sun with their new solar telescope.
From the article:
The photographs reveal never-before-seen details of solar magnetism revealed in photospheric and chromospheric features.
“With our new generation visible imaging spectrometer (VIS),” said Wenda Cao, NJIT Associate Professor of Physics and BBSO Associate Director, “the solar atmosphere from the photosphere to the chromosphere, can be monitored in a near real time. One image was taken with VIS on May 22, 2013 in H-alpha line center. The lawn-shaped pattern illustrates ultrafine magnetic loops rooted in the photosphere below.”
The other photospheric photograph is the most precise sunspot image ever taken: A textbook sunspot that looks like a daisy with many petals. The dark core of the spot is the umbra and the petals are the penumbra. “With the unprecedented resolution of BBSO’s NST, many previously unknown small-scale sunspot features can now be perceived,” said Cao. In particular, there are the twisting flows along the penumbra’s less dark filaments, the complicated dynamic motion in the light bridge vertically spanning the umbra’s darkest part and the dark cores of the small bright points or umbra dots.
Peter T. Hoss has penned an editorial for the Monterey Herald about the idiotic Draft Merced River Plan. In it, he lays out issues with the plan which I wholeheartedly agree with.
On this day in 1864 President Lincoln signed a bill drafted by both houses of the 38th Congress of the United States officially creating the Yosemite Grant. While Yellowstone ultimately became the first National Park, this was the first instance of park land being set aside for preservation and public use by the federal government. The grant was the result of citizens like Galen Clark and Senator John Conness advocating heavily for protection of the area. John Muir later led a successful movement to establish a larger national park encompassing not just the Yosemite Valley, but surrounding mountains and forests as well.
With their usual regard for conservation and the environment, the Los Angeles Department of Water & Power (DWP)continues to display their professional ineptitude and scandalous behavior. All efforts to protect and restore Mono Lake have been undermined by the DWP since they made a unilateral power-grab of lake monitoring operations and started diverting $10,000,000 in water per year. Everything the DWP is doing is directly in violation of the rules set in 1998 by the State Water Board.
